Actually, yes. My primary strategy is to hold at least 30% of my entire wealth in bitcoin, because this is what i believe in.
I did it in the past .... one day bitcoin will fall . And selling it will be impossible. It need to hedged.
To hedge it you need financial tools like options, future contracts and others.
I'm not talking about investment into a business.
The investment I'm talking about is a speculation on prices of other securities to protect my wealth.
